Java 有没有一种方法可以通过ApachePOI从给定的PowerPoint文件中准确地获取演讲者笔记？

我正在尝试使用ApachePOI将演讲者笔记从一个powerpoint传输到另一个powerpoint，但无法获得准确的传输

环顾四周后，我找不到很多资源。我确实找到了这个链接：，它在大多数情况下都有效。但是，当原始pptx中包含幻灯片母版等功能时，一些不属于演讲者备注的文本将被解释为演讲者备注

XSLFNotes notes_src = slides_src[i].getNotes();
XSLFNotes notes_dst = ppt_dst.getNotesSlide(slides_dst[i]);

这都在for循环中，其中i是迭代数。在这里，我得到了源的幻灯片I和目标文件中相应的幻灯片I

for (XSLFShape shape_src : notes_src) {
    if (shape_src instanceof XSLFTextShape) {
        XSLFTextShape txShape = (XSLFTextShape) shape_src;
        for (XSLFTextParagraph xslfParagraph : txShape.getTextParagraphs()) {

这是我从幻灯片上得到的文本。下面的if循环是我必须开始过滤掉一些“演讲者”笔记的地方，这些笔记实际上不是演讲者笔记（例如，幻灯片编号以某种方式被解释为笔记；还打印了这个版权符号）

简言之，不是演讲者笔记的东西会以“笔记”的形式出现。网上关于这个主题的资源不多；有人能帮忙吗？

得到的是notes幻灯片。这些可能不仅包含注释的正文文本形状，还包含通过其他占位符（如页眉、页脚、日期时间和幻灯片编号）填充的文本形状。要确定所获得的文本形状的类型，可以从该形状获取占位符类型。这是

CTShape cTShape = (CTShape)shape.getXmlObject(); 
STPlaceholderType.Enum type = cTShape.getNvSpPr().getNvPr().getPh().getType();

然后只能得到

STPlaceholderType.BODY

类型的文本形状

例如：

import java.io.FileInputStream;

import org.apache.poi.xslf.usermodel.*;

import org.openxmlformats.schemas.presentationml.x2006.main.CTShape;
import org.openxmlformats.schemas.presentationml.x2006.main.STPlaceholderType;

import java.util.List;

public class PowerPointReadNotes {

 public static void main(String[] args) throws Exception {

  XMLSlideShow slideShow = new XMLSlideShow(new FileInputStream("PowerPointHavingNotes.pptx"));

  List<XSLFSlide> slides = slideShow.getSlides();
  for (XSLFSlide slide : slides) {
   XSLFNotes notes = slide.getNotes();
   for (XSLFShape shape : notes) {
    CTShape cTShape = (CTShape)shape.getXmlObject();
    STPlaceholderType.Enum type = cTShape.getNvSpPr().getNvPr().getPh().getType();
    System.out.println("type: " + type); 
    if (type == STPlaceholderType.BODY) { // get only shapes of type BODY
     if (shape instanceof XSLFTextShape) {
      XSLFTextShape textShape = (XSLFTextShape) shape;
      for (XSLFTextParagraph paragraph : textShape) {
       System.out.println(paragraph.getText());
      }
     }
    }
   }
  }
 }
}

import java.io.FileInputStream;

import org.apache.poi.xslf.usermodel.*;
import org.apache.poi.sl.usermodel.Placeholder;

import java.util.List;

public class PowerPointReadNotesHL {

 public static void main(String[] args) throws Exception {

  XMLSlideShow slideShow = new XMLSlideShow(new FileInputStream("PowerPointHavingNotes.pptx"));

  List<XSLFSlide> slides = slideShow.getSlides();
  for (XSLFSlide slide : slides) {
   XSLFNotes notes = slide.getNotes();
   for (XSLFShape shape : notes) {
    Placeholder placeholder = shape.getPlaceholder();
    System.out.println("placeholder: " + placeholder); 
    if (placeholder == Placeholder.BODY) { // get only shapes of type BODY
     if (shape instanceof XSLFTextShape) {
      XSLFTextShape textShape = (XSLFTextShape) shape;
      for (XSLFTextParagraph paragraph : textShape) {
       System.out.println(paragraph.getText());
      }
     }
    }
   }
  }
 }
}

因此，不需要直接使用低级
